These ACCO self-adhesive fasteners are the economical way to keep documents from falling out of folders and getting lost. Each fastener has a peel away backing over a permanent adhesive that holds fasteners securely in place. Strong tin plating over a steel base ensures you will have a strong fastener, yet it will still look good in presentations. A handy positioning guide on each box of 100 assures correct placement. ACCO self-adhesive fasteners can be used with the 70014 compressor (sold separately) for secure hold. ACCO combines quality, style and innovation to become your total resource for accounting and storage supplies.
